I too realized the rivers map should be updated because the rivers don't match with the coasts (for example the Nile Delta) or with the borders (for exemple Gambia and surroundings)
I think this is because the rivers map was done with an older version of q-bam map

I have, over the years, trawled the internet to find basemaps to use and have even created my own. To save others that trouble I have collected the ones I consider the best together here for anyone to use. Unlike the Q-Bam world maps, Europe does not have a standard format size so I am...

I put this together as a rough map based on a 2014 request that was never satisfied.
Now that the main Q-Bam is done {if anyone has the time or inclination] maybe the Pacific oriented Q-Bam could be the next project?

I just found out that the eastern part of the Oregon-Washington border is one pixel higher than the North-South Dakota border. Both borders are defined along the 46th parallel, and from what I can tell based on the Oklahoma-Kansas (37th parallel), Kansas-Nebraska (40th parallel), Nebraska-South Dakota (43rd parallel), and US-Canada (49th parallel) borders, it's more likely that it's the Oregon-Washington border that is misplaced by one pixel, and therefore also misplaced other historical borders in the borderpool.
